Do you know how far phototoxicity can hinder your experiments?🤔 @mariodelr.bsky.social and @gomez-mariscal.bsky.social have just published their work on #PhotoFiTT in @natcomms.nature.com where they explain how to quantitatively measure it in live-cell imaging.⚡🧫🔬

🚨Amazing news for a cloudy Monday!🌩️😎 I'm extremely happy to share that our last adventure is finally out!🚀🎉Phototoxicity fitness time trial (#PhotoFiTT) - a quantitative framework for assessing phototoxicity in live-cell microscopy experiments 🔬❤️🔥⚡️ doi.org/10.1038/s414...
🎉 Last but not least, a huge thanks to @gomez-mariscal.bsky.social Leonor Morgado, Raquel Portela, @guijacquemet.bsky.social @microbematos.bsky.social @henriqueslab.bsky.social
We have been an amazing team, and you made this work possible! 🥳🚀
🛠️Why this matters: PhotoFiTT empowers labs to fine-tune imaging conditions, improve reproducibility, reduce cell stress, and strengthen biological conclusions. All code, data & tools are open on GitHub & BioArchive 🔓📦 #OpenScience 👉 github.com/HenriquesLab...
💡 Key insights we uncovered: Near-UV light delays mitosis at doses as low as 0.6 J/cm². Longer wavelengths need higher doses, and surprisingly, continuous low-intensity illumination (slow scan) can be more damaging than brief high-intensity bursts (fast scan). Data-driven phototoxicity thresholds! ✨
🚀 Enter PhotoFiTT: a standardise experimental protocol combined with AI-powered image analysis to track cell behaviour (mitosis, size, activity) in response to light exposure. What’s even better: label-free and fully quantitative! 🔍🤖
The challenge: live-cell fluorescence microscopy can unintentionally stress or harm cells, changing timing, size and activity. If left unchecked, this can skew biology and standard qualitative checks just don’t cut it ⚡️ #Microscopy #CellBiology
It’s FINALLY out! 🎉🚀 We have been working on PhotoFiTT for a long time, and it’s now published, introducing a quantitative framework to measure phototoxicity and optimise live-cell microscopy experiments. So excited to finally share the last version! 🔬✨ #PhotoFiTT doi.org/10.1038/s414...
Fantastic work! Elegant experimental evolution with big implications for how cell size can evolve without compromising fitness. Congrats to Ana and collaborators, definitely worth a read for anyone into cell cycle, size control, or evolution 🧬🔄
Our Researcher @mariodelr.bsky.social and Raquel Portela from @microbematos.bsky.social were invited by @healthnewspt.bsky.social to talk about their new collaboration project awarded by Early Career Research Award, 𝗜𝗻𝗳𝗲𝗰𝘁𝗼𝗙𝗶𝗧𝗧.

Workshop attendees grouped together. In the background there are trees and mountains. The Workshop title is Democratising Microscopy in Latin America: Imaging Across Scales and Regions, and it took place in Banos, Ecuador on 12-15 October 2025.
Thank you to the organisers Constadina Arvanitis, @mariodelr.bsky.social, Helena De la Torre, @marianadeniz.bsky.social, María Fernanda Latorre Barragán and Licyel Lenny Paulas Condori.
